On Tuesday, Microsoft signed a patent cross-license agreement with Amdocs Software Systems. They specifically noted in their press release that the agreement covered Amdocs' use of 'Linux-based servers in its data centers,' and noted that Amdocs paid them money for the privilege. In light of the current state of mobile device licensing, with Microsoft getting a cut from most Android device sales, should data centers operators worry about having to pay Microsoft for their use of Linux servers? From the article: "To date, Linux advocates have been hypersensitive to any move Microsoft has made against the open-source OS—which, to be fair, Microsoft has seen as a threat since its inception. It's certainly possible that Amdocs approached Microsoft for a patent cross-license for its own purposes; but if that's the case, Amdocs would likely have disclosed that fact. Amdocs representatives declined to comment on the deal, and the arrangement has been completely ignored on the Amdocs Website. ... The question, though, is whether Microsoft will begin eyeing data-center operators as a similar source of licensing revenue. The company has avoided directly challenging Linux developer/distributors such IBM or Red Hat, instead targeting partners and customers."
